One of the problems in Progo River is the forming of erosion and sedimentation that caused change to river morphology. Hydraulics parameters play important role in the process of sedimentation and degradation/erosion at the bottom of the river. Regarding these conditions, to examine the potential of bank erosion, we need the analysis of hydraulics condition in the Progo River using software sms 10.1 (surface water modeling system). The hydraulics parameters include current patterns, flow direction, and flow velocity on the Progo River. The results of the study shower velocity flow on the area around the Bantar bridge are not similar the field survey velocity. The flow pattern in the Progo River is influenced by the changing shape of the river.
